value

Method Detail

getKey

getValue

Get the value. Note: In an entrySet or entrySet.iterator,
unless the set or iterator is used under synchronization of the
table as a whole (or you can otherwise guarantee lack of
concurrent modification), getValuemight
return null, reflecting the fact that the entry has been
concurrently removed. However, there are no assurances that
concurrent removals will be reflected using this method.

setValue

Set the value of this entry. Note: In an entrySet or
entrySet.iterator), unless the set or iterator is used under
synchronization of the table as a whole (or you can otherwise
guarantee lack of concurrent modification), setValue
is not strictly guaranteed to actually replace the value field
obtained via the get operation of the underlying hash
table in multi-threaded applications. If iterator-wide
synchronization is not used, and any other concurrent
put or remove operations occur, sometimes
even to other entries, then this change is not
guaranteed to be reflected in the hash table. (It might, or it
might not. There are no assurances either way.)
